Adult COVID-19 Vaccination Status and Intent by Demographic Group

Survey data from the National Immunization Survey Adult COVID Module (NIS-ACM) provides estimates of vaccination status and intent. The CDC publishes these metrics by demographics, including group categories, geography, and time period. Data was last updated in August 2023.

Use Cases

• Analyze trends in vaccination intent over time using the 'Year', 'Time Period', and 'Estimate (%)' columns.
• Compare vaccination estimates across demographic segments using the 'Group Category' and 'Group Name' columns.
• Assess geographic variation in vaccine confidence by joining on the 'Geography' and 'Geography Type' fields.
• Evaluate statistical precision of survey estimates using the 'Sample Size' and '95% CI (%)' columns.
• Identify data suppression for small sample sizes by filtering on the 'Suppression Flag' column.

Strengths

• Includes statistical confidence intervals ('95% CI (%)') for each estimate.
• Provides demographic breakdowns via multiple 'Group' and 'Indicator' columns.
• Data is sourced from a national survey conducted by the CDC.

Limitations

• A known data processing error from August 2021 affected categorization for MSA status, SVI, and political leaning estimates.
• Sample sizes for specific demographic or geographic groups may be small, leading to data suppression.
